Active airflow temperature controlled bedding systems

Abstract

A climate controlled bedding system includes at least one coil spring layer; and an air supply fluidly coupled to the one or more fluid conduits. In some embodiments, a filter is disposed within a flow path of a fluid conduit.

What is claimed is: 
     
       1. A climate controlled bedding system comprising:
 a base layer comprising a planar top surface including one or more fluid conduits extending to the planar top surface, and an air supply device disposed within the base layer and fluidly coupled to the one or more fluid conduits; 
 a layer overlaying the base layer, the layer comprising a manifold of one or more perforated conduits in fluid communication with the one or more fluid conduits extending in the base layer to the planar top surface, wherein the one or more perforated conduits are disposed at about an upper portion of the layer, and the layer further includes foam intermediate the one or more perforated conduits, the foam having a thickness that is equivalent to a diameter of the one or more perforated conduits, and the foam collectively defining a top planar surface of the layer with the one or more perforated conduits, wherein the one or more perforated conduits are configured to discharge air along a length of the one or more perforated conduits; 
 a coil spring layer overlaying the layer comprising the one or more perforated conduits, wherein the coil spring layer is in direct contact with the top planar surface of the layer defined by the foam and the one or more perforated conduits; and 
 an uppermost foam layer overlaying the coil spring layer, the uppermost foam layer including a support surface adapted to substantially face a user resting on the bedding system. 
 
     
     
       2. The climate controlled bedding system of  claim 1 , further comprising a filter disposed within a flow path of a fluid conduit. 
     
     
       3. The climate controlled bedding system of  claim 2 , wherein the filter further comprises a fragrance pad. 
     
     
       4. The climate controlled bedding system of  claim 2 , wherein the filter further comprises an activated carbon treatment. 
     
     
       5. The climate controlled bedding system of  claim 2 , wherein the filter further comprises an antimicrobial coating thereon. 
     
     
       6. The climate controlled bedding system of  claim 1 , wherein the coil spring layer comprises pocketed coil springs. 
     
     
       7. The climate controlled bedding system of  claim 1 , further comprising a perforated foam layer intermediate the coil spring layer and the layer comprising the one or more perforated conduits. 
     
     
       8. The climate controlled bedding system of  claim 7 , wherein the perforated foam layer is an open cell foam. 
     
     
       9. The climate controlled bedding system of  claim 7 , wherein the perforated foam layer comprises a plurality of opening extending from a bottom surface to a top surface. 
     
     
       10. The climate controlled bedding system of  claim 1 , wherein the one or more perforated conduits comprise asymmetric perforations oriented to flow air in an upwards direction relative to ground. 
     
     
       11. The climate controlled bedding system of  claim 1 , wherein the air supply device is selected from the group consisting of a fluid transfer device, a thermoelectric device, a convective heater, a heat pump, a dehumidifier and combinations thereof. 
     
     
       12. The climate controlled bedding system of  claim 1 , wherein the one or more perforated conduits laterally extend from a head end to a foot end and/or transversely extend from side to side.
